Yield response across four planting dates

Yield response for four harvest plant populations averaged across four planting dates for two studies. Study 1
was conducted at Ames, Crawfordsville, and Nashua from 2003 to 2005. Study 2 was conducted at DeWitt, Nevada, and Whiting from 2004 to 2006. Yield values are not significantly different from each other when the difference between values is less than the LSD.
